Fire, air, water and earth: Using fossils to discover the evolution of Australia’s open vegetation. How Australia came to be dominated by open, tough-leaved vegetation is an old but still highly controversial question, especially with recent developments in molecular biology that challenge paradigms established from the fossil record. The project will test this new molecular paradigm with innovative use of characteristics of fossil leaves to identify the timing and drivers of the evolution of Au ....Fire, air, water and earth: Using fossils to discover the evolution of Australia’s open vegetation. How Australia came to be dominated by open, tough-leaved vegetation is an old but still highly controversial question, especially with recent developments in molecular biology that challenge paradigms established from the fossil record. The project will test this new molecular paradigm with innovative use of characteristics of fossil leaves to identify the timing and drivers of the evolution of Australia’s open vegetation. The integration of new and rigorous evidence derived from living and fossil plants will provide the clearest evidence yet for the origins of Australian environments. This has ramifications for understanding plant responses to past and future climate changes.Read moreRead less
Integrating fossils and genomes to resolve the early evolution of snakes. This project aims to address a high-profile evolutionary controversy – the origin of snakes – by reconciling the anatomical and fossil evidence with the burgeoning genomic data. New genomic data surprisingly links snakes with the un-snakelike iguana, prompting claims that the genetic and the fossil/anatomical data are irreconcilable. The project aims to evaluate these key fossils, and reptile anatomy in general, in light o ....Integrating fossils and genomes to resolve the early evolution of snakes. This project aims to address a high-profile evolutionary controversy – the origin of snakes – by reconciling the anatomical and fossil evidence with the burgeoning genomic data. New genomic data surprisingly links snakes with the un-snakelike iguana, prompting claims that the genetic and the fossil/anatomical data are irreconcilable. The project aims to evaluate these key fossils, and reptile anatomy in general, in light of the new genomic tree. This has potential to greatly elucidate major evolutionary changes across the lizard-snake transition (for example, extensive mobility in the snake skull). The project also plans to assess the long-term evolutionary consequences of ‘snakiness’, such as the hypothesised irreversibility of limb loss, and increased resilience to mass extinction.Read moreRead less
Capturing Proteus: 65 million years of ecosystem change revealed through evolution of Proteaceae in Australasia. By assessing past changes in the iconic Australian plant family Proteaceae, this research will show how the Australasian vegetation has responded to 65 million years of profound landscape and climate changes. This knowledge from the past will give important insights into how ecosystems can be expected to change under future climate scenarios.
